不同留茬收获模式对红麻产量及营养价值的影响初探

Effects of Different Stubble Patterns on Yield and Nutrient Composition of Hibiscus cannabinus

以代表性红麻品种中红麻318为材料,对红麻留茬收获模式进行初步探究,通过不同留茬收获方式对产量、营养价值的影响进行比较,筛选出使红麻具有较高产量和营养价值的收获方式,为红麻饲用价值的开发和利用提供参考。结果表明:90 cm留茬高度试验组在整个生长期的干物质产量(15943 kg/hm^2)和粗蛋白产量(1613 kg/hm^2)均高于60 cm试验组和120 cm试验组。

This study aimed to evaluate the different stubble patterns of Hybrid Kenaf 318 （Hibiscus cannabinus （kenaf） China）.Comparing the effect of different stubble patterns on the yield and nutrition of Hybrid kenaf 318,the best method was selected out.The results showed that the dry matter yield （15943 kg/hm^2） and crude protein yield （1613 kg/hm^2） of the 90 cm stubble height group at the whole growth stage were higher than those of the 60 cm test group and the 120 cm test group.Kenaf as a forage crop is similar to general forage at the stubble cropping model.The results of our trial revealed that 90 cm stubble was the most suitable height for harvesting.
